To all whom t 171mg/ con cern Be it vknown that 1, NORMAN L. Hsin', a citizen ofthe United States, residing l:at Capel Girardeau, county ofv Cape` Girardeau,

and State of Missouri, haveiinvented eertain newtandv useful Improvement in-Du-inping Hoists, ofwhichthefollowing: is a speciiicatiom'reference beinglhadto the accompanying fdrawings, forming v:L -,part thereof.

.This invention: relates .generally to hoisting apparatus,,andymore particularly, toa certain c.new .and useful.improvementin a type of hoisting apparatus .that may descriptively .designate as .a .dumping-hoist.

My .invention has j forA its chief object the provisionofa duI-npingA apparatus or hoist including a traveling bucket or .car and trackways' so constructed and co-operating to ciliciently, positively, and automatically effects dumping tiltof the bucketor car.

With thev above and other-'objects in view, .my invention 1 resides in i the novel features of form, construction, arrangement, and combination of parts .hereinafter described 25 andpointedont in the claims.

-ln the accompanying drawing,

Figure i .is a `reducedelevational view of `a dumpingapparatus or hoist constructed in accordancewithand embodying my-invention, portions of the shaft-framework lacing, omittedtotmore clearly showL one set of the. shaft traclnways;

Figure 2 illustrates the-hoisting or elevating-shaft and its trackvvays in transverse section and the hoisting and. dumping bucket or car in plan;

Figure l3 is-.an enlarged :frag-mental elevational view of onefset of the shaft trackways vand FigureV 4- is a detail section taken approximately on the line 4-4f, 'Figure 3.

`Referring now'more in detail-iandfby reference characters to the accompanying .drawings, which'illustrate a preferred embodiment of vmy invention, A f designates the hoisting or elevating `shaft proper, which, as best seen in Figures l and v2, is constructcd preferably of suitable structural steel longitudinal or 'vertical membersA 1 and lateral or cross mem-bers -2 rsuital'ily riveted or otherwise rigidly fixed together andlpreferably reeenforced and tbraced by lacingmembers 53. The 'shaft frame-work is rested a-ndbuilt uponasuitable foundation,is of suitable height, andi is of suitable interior dimensionslor `cross area to accommodate a hoisting -and .dumping .bucket or @oar B. Forming substantiallya part `of the shaftfA and-leading fromthe shaft Apreferably 4at a point intermediate .its `ends =to a rock- Crusher or` the like C, is achuteiD. Rigidly fixed ,tofdand upon the inner (faces Vof Vopposite wallsof the frame-work of shaft A and disposed vertically. in, parallel. registration are 4track-ways T .eachfformed offsuitably spaced opposed. angle-members .4, 4,', as clearly. shown in A Figureg, .and Inmay herel state that thetrack-ways 'D extendvertically within shaft A from a `.point adjacent its lowerend to a point-suitably adjacent the chutefD.

The bucket or carfB isi-.also preferably of rigid steel construction, open at one or its so-calle'd upper or frontrendysuitably vprovided at its other orso-called loweror rear end with a cross-shaft 5, .and suitably provided upon one side with pairsA of front. and rear wheels or rollers-"6, 6, and 6 6', respectively, all of a diameter to more or less snugly it for rolling movement upon and between the opposedangles 4, 4 of the trackways T, as also clearlyfseenin Figure 2.v Pivotally connected `at oneend to the endsof the `bucket shaft 5, are linksor' bails 7, .and reaved .upon suitable Ipulleys or sheaves Sfmounted lfor rotationA upon andat the 'upper end of the .shaftfraine-'Worln fastenedk at Vone end to .the free ends of the links or bails'?, andsuit'ably fastened `at their other end to the drum or drums of`a suitable hoisting engine, not shown, Vare -hoistingcables 9. It will be lobvious that, as the cables '9 are wound upon or permitted to unwind from the hoisting drum or drums, the bucket or car B will be hoisted or elevated or kpermitte'dto drop or descend in the -shaft A; the trackways yT, in their described engagement withy the ear rollers' or wheels 6, 6', maintaining ,the `bucket in proper ma-terial-carrying position and facilitating smooth travel ofthe buckety up :and down inthe shaft A.

Riveted or otherwise yrigidly vfixed flatwise upon .a wall ofthe shaft frame-work and at the upper "end ofthe tixedtrackway T, are plate-sections 10. .In Figure- 3, one

set of such plate-sections 10, and their associated parts, now to be described, are shown, and it will be understood that a second set of such plates 10 and their associated parts are in opposed relation duplicated and similarly located upon the opposite wall of the shaft A.

Riveted upon and preferably at one margin of the plate-sections 10, is an anglemember 11, which at its inwardly projecting or presented leg or portion forms a fixed continuation of the inwardly presented leg or portion of the angle 4 of the trackway T. For substantially the greater part of its length, as at a, the angle 11 also aligns vertically with the angle 4; adjacent its upper end, however, the angle 11 is arcuated or rounded, as at b, on an arc preferably of approximately and then reversely arcuated and again continued vertically upwardly for a relatively short distance, as at c.

Riveted upon and preferably at an opposite margin of the plate-sections 10, is a second angle-member 12, which likewise at its inwardly projecting leg or portion forms a fixed continuation of the inwardly presented leg or portion of the opposed angle 4 of the trackway T. For a part of its length, the angle 12, as at d, extends obliquely upwardly from the angle 4 and away from the portion a of the angle 11. The angle 12 is then, beginning on a line substantially coincident with the base or lowerend of the arcuated portion Z) of angle 11. gently areuated first outwardly, as at c, and then inwardly, as at 7', throughout the remainder of its length, thel upper end of the angle 12 being located upon the shaft framework at some suitable distance vertically above the plane of the upper end of the vertically projecting portion c of the angle 11.

13 designates a third angle-member, which is likewise gently arcuated substantially throughout its length in conformity with and corresponding to the curvature of the portions c and of the angle 12, and which is also riveted or otherwise fixed up* on the plate-sections 10 in suitably spaced and opposed trackway forming co-operation with said portions c and f of the angle 12 and in spaced or broken relation to the fixed trackwa-y T. Projecting vertically from the upper end of the angle 13, is a relatively short continuation 14, for purposes shortly appearing, and to facilitate dumping and return movements of the car B, more fully hereinafter described, the angles 12 and 13 slightly flare oppositely outwardly at their upper ends only, as shown in Figure 3,

Pivoted intermediate its ends, as at 15, 'for swinging mov-ement upon and relatively to the fixed plate-sections 10. is a switch plate-section 16 preferably having in elevation the form or configuration best seen in Figure 3.

Fixed upon and at one margin of the plate 16, is an angle 17 opposed to and adapted for trackway forming cooperation with the portions a and b of the fixed angle 11, the angle 17 similarly comprising a straight portion g and an arcuated portion L.

Fixed upon and at the opposite margin of the plate 16, is an angle 18 opposed to the portion Z of fixed angle 12 and adapted in movable or switching continuation of the fixed angle 13 for trackway forming cooperation with said portion d of the angle 12. The angles 17 and 18 are disposed obliquely relatively to each other and at their lower ends converge and form the switchpoint e' of the switch-plate or member 1G, as clearly seen in Figure 3. Preferably the angle 18 is continued, as at y' and 7c, around the margin of the plate 16 and connected at its upper end to the upper end of the angle 17 by a cross-angle-piece 19 adapted, as more fully hereinafter appearing, to forni a car or bucket stop.

Normally, as under the pull of gravity or other suitable means, the plates 16 occupy the position shown in Figure 1, with their switch-points i registering with the angles 4 of the fixed trackways T. As the car B is hoisted, its front pair of wheels 6 first pass from the tracliways T and enter the continuation or branch track-ways formed by the opposed angles 11 and 17. As the hoisting of the car B continues, its front wheels 6 engage and roll upon the opposed portions Z) and /L4 of the angles 11 and 17, whereupon the switch-plates 1G are automatically swung and their switch-points z' thrown into registration with the opposite angles 4 of the trackwa-ys T or into the position thereof illustrated in Figure 3, and I may here state that the track-ways and the space or dimension between the pairs of wheels 6 and 6 of the car B are so relatively proportioned that the switclrpoints t' are so thrown on the upward travel of the car approximately when the rear wheels 6 of the car are about to leave the fixed shaft track-ways T. The switch points e' being so thrown, the front wheelsA 6 of the oar, on continued upward movement thereof, will travel in the trackways formed by the portions and 7L of the angles 11 and 17 and the rear wheels G of the car will be shunted to travel in the track-ways formed by the angle 12 and its opposed angles 1S and 13, and in such continued upward travel, the car B, through and by the described formation of the trackwaysvand the hoisting links 7 and their connection with the cables 9, will be gradually tilted, swung, or upset into the dumping position thereof illustrated in Figure 1 or until further movement of the car is stopped ies by the. upward continuations c fand-14 of the angles 11 and 13, respectively. lVith the car lf3 in such tilted ondumpifngposition, the switch-members y16 lautomatically swing or 'returnv tov normal position, carrying their switch-points z' again intofregistration with the'langfles tot the'iiiXed trackways T and at Athe same'time-disposing the angles 19 immediately behindV the bucket front-wheels 'T-h'e'oar being lsotillted anddumped and the cables 9 being `now p'erniittedto unwind from their hoisting drums, the rear wheels G ofthe car Bwill now tirst reversely or downwardly travellin the trackway termed by the iixedportionse and f ot thcf angles 12Vv and the opposed-angles 1:3, the car at its front wheels being held trom movement by the angles .19 shifted v'or-interposed to the rear thereof when the plater16 is in normal position. The rear wheels. ti continue to so travel 'downwardly until they enterl the trackways formed by the portions tl-ot the angles 12 and the opposed switchangle-1'8, whereupon theplates 16 are again automatically swung and their switch pointez' thrown into registration with iixed track-angles fl, when the front wheels G of the car are again free to nieve downwardly. As the car continues to move or travel downwardly,'its front wheels 6 now again enter intermediate'the opposed angles/11 and 17, and as the bucket continues to `further traveldownwardly and when both its pairs oi wheels enter thetined-traclzways T, the switch'nplates y16 automatically return vto normal position, lwith their switch-points in registration withthe `angles 4 of the traclzways T,^ready for a second car-dumping operation.

vThus, my newdumping hoistv or apparatus is automatic and positive iny itsaction and works hand-inhand `with the load carrying car as the car is hoisted and, in turn, permitted to drop in the'shatt. Preteral'iiy, stops QGare' fixed on the plate-sections 10 to limit the swinging ymovementmt'ithe platesections 16 when actuated by the-rear carwheels G on downward travel of the car.
